Jabari is power washing houses for a summer job. For every job, he charges an initial fee plus $30 for each hour of work. His to
guapka [62]

Answer: f=30t+50


Step-by-step explanation:

Given: Jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job.

For every job, he charges an initial fee plus $30 for each hour of work.

let m be his initial fee.

Then f=30t+m.......(1)

Also, his total fee for a 4-hour job, for instance, is $170.

Put t=4 and f=170 in (1), we get

170=30(4)+m\\\Rightarrow170=120=m\\\Rightarrow\ m=170-120\\\Rightarrow\ m=50

Now, put m=50 in the (1), we get the function's formula for Jabari's total fee, f as

f=30t+50
